Abstract:
The report presents the problem of detecting cracks in the crane structure by natural frequencies. In that, the most important is the research of the computational effect of crack on natural frequencies which makes the database develop a procedure for determining a crack. However, measuring the natural frequencies needs to choose an agitated method (cause shakes) for it. The authors also present the results of the features dynamic response of the tower structure endured to moving load on the bridge of the tower structure. This result shows that it is possible to use the normal working state of the tower structure when moving load along the bridge to cause the necessary oscillations to measure the natural frequencies.
